Buying advice

When choosing a doorbell transformer, consider the voltage and VA (power) requirements of your doorbell. Most standard mechanical doorbells work with 16V 10VA, but smart doorbells often need 16V 20-30VA or 24V. Check your doorbell specs before buying. Also, ensure the transformer is UL listed for safety and check compatibility with your chime. For outdoor installations, choose one with a weatherproof housing.
